Merge branch 'fixes' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM fixes from Russell King: "The largest thing in this set of changes is bringing back some of the ARMv3 code to fix a compile problem noticed on RiscPC, which we still support, even though we only support ARMv4 there. (The reason is that the system bus doesn't support ARMv4 half-word accesses, so we need the ARMv3 library code for this platform.) The rest are all quite minor fixes." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: 7490/1: Drop duplicate select for GENERIC_IRQ_PROBE ARM: Bring back ARMv3 IO and user access code ARM: 7489/1: errata: fix workaround for erratum #720789 on UP systems ARM: 7488/1: mm: use 5 bits for swapfile type encoding ARM: 7487/1: mm: avoid setting nG bit for user mappings that aren't present ARM: 7486/1: sched_clock: update epoch_cyc on resume ARM: 7484/1: Don't enable GENERIC_LOCKBREAK with ticket spinlocks ARM: 7483/1: vfp: only advertise VFPv4 in hwcaps if CONFIG_VFPv3 is enabled ARM: 7482/1: topology: fix section mismatch warning for init_cpu_topology
